NO, read my write up on how to remove the front bumper. You can use the same large push pin connectors that are used to hold the grille on and delete the rivets completly. I just "borrowed" 2 from the grille for now until i get more. So i only have 1 push pin on each side right now and its been fine. no need to buy the rivet gun or rivets if you dont need to.

Why? I will order more push pins soon but they are more then adequate. I only have 1 on each side right now and its fine. does not move at all. When i put 2 on each side it will be just as strong as the rivets. its not going to flap in the wind. all its holding is the fender well liner. the guys that lift these things tear the fender well liners out. its not structural. and its an easy fix to the rivets.

those can be removed...fall out too easy. I have seen it. When i went to the 09 SRT bumper the body shop put one of those on mine and it was half way out in just a couple days. Plus....when I had the liners loose with no rivets...I drove it and the liners rubbed on the front tires. Needless to say it shredded the liners and I had to buy new ones.....not pretty at all....

Well mine have been fine with only 2 push pins, 1 on each side for 2 months now. I have just been too lazy to buy more. I have a bag of rivets too but no rivet gun as i am too cheap to buy one.

Will a standard large rivet gun work on the plastic rivets?

From what I have seen no, the rivet guns sold at local stores for use with metal rivets will not work, they are too small to accept the larger plastic posts on the plastic rivets. When I did my ground effects kit I went everywhere trying to buy a rivet gun locally and came up with nothing that will work. I ended up setting the rivets by hand, I used a close end wrench pushing the plastic rivet tight to the car then a set of pliers to pull the post outwards. It took alot of power but I got them to set very tight. But I do recommend buying the plastic rivet gun, I found it as cheap as 20 bucks plus shipping online.

Basically how I set the rivets on the car. I did all my ground effects this way and they are still 100% tight.

Before installing them I softened the plastic by pushing down on the rivets a few times by hand.
